of the cover being to regulate the opening in the box so as to give a larger or'smaller flame. This cover carries 0. depending damper or valve plate 7 which normally reaches within about a quarter of an inch of the bottom of the box. The purpose of this damper plate is to control the quantities of air admitted into the firebox and to create a" strong draft close to the bottom of the box. This damper plate may be mised more or less by means ofthe wedge-member 8 which is carried by the'rodor handle 9, which extends out through the opening 3 in the box and is slidable in suitable guides 215.10. The movements of'the cover plate are effected by means of a suitable handle or rod venient reach of the'operator.

Oil for fuel purposes is admitted up through the pipe 12 into the box A at any convenient point between the outer end of the box and the cross-bar or bafiie 13 in the This baffle 13 is about one-quarter l] which also extends outward to a point .within conoi an inch in height and forms a dam behind which a limited quantity of oil may accumulate. Thefrontend wall of the box is high enough so that the oil will first overflow the baffle 13: The rod 9 is sufficiently cut out as shown at 14 to accommodate the baffle 13, and when the cover 5 is drawn outward to open up the box to its fullest capacity the damper 7 will not be drawn back beyond the batlle.

In operation the oil is admitted in a suitable quantity through the oil pipe 12 into the box A, the latter being arranged at a slight incline in the stove so that the oil naturally flows by gravity toward the inner end. When some'ol' the oil has passed over the battle and undemeath the draft plate 7 to the inner end of the tirebox and the cover having been sufiiciently drawn back, the oil is ignited. As the heat rapidly increases the box-becomes heated up and the oil becomes volatilized shortly after entering the box A'. By reason of the draft induced by the burning gases in the space on the inner side of the damper 7, the oil vapors and a suitable quantity otair'irom the outside, is drawn in with a swish und erneath the damper plate 7 and becomes ignited inside the box A. The volume of flame passes'out through the opening in the top of the box A regu latcd according to the size of the top opening in the box A. The mixed air and inflammable gas are drawn underneath the plate 7, strike the rear end of the box A and are deflected upward to be met by the overhanging ledge 4 whereupon. they are again directed horizontally toward the front of the box; this setting up a swirling motion in the box A and insuring a perfect;

mixture and a more perfect combustion.

If the ledge 4 or some equivalent substitute for it was omitted, the mixture would not beso good, and moreover all the flame would be banked up at one end of the firebox, which would be bad. As it is the swirling acin underneath the damper 7 to lift the latter and consequently increase the draft opening. By moving the cover 5 forward and back, a larger or smaller flame results. I

The quantity of oil red to theburner may be regu- 10 lated by a suitable cock 15. In order to guard against overflow in case the fire should'go out or for any other reason, I may employ the following simple means: Adjacent to the outer end of the box A is formed a small pocket 16, the rim of which is slightly above the level of the baffle 13. This pocket 16 connects with a drain-pipe 17 which is adapted to discharge into a cup 18 carried by a lever 19 which controls a cL1t-ofi-valve 20 in the oil feed pipe 12. This latter valve is normally held open by means of a spring 21. In the event that 20 the box A should fill up with oil so that the surplus overflows into the drain pipe-l7, the cup 18 will finally accumulate a sufiicient load to overcome the'tension of the spring 21 and rock lever 19 to close the valve 20 in the oil feed pipe and so cut oii the further flow 01' oil to 2 5 the burner until the cup 18 has been emptied.

Having thus described my invention, What I claim and desire to secure by Letters Patent, is-

1. An oil burner having in combination a box-like structure, open at the top and at one end; a movable coverplate for the open top of the box, a movable clampenplate carried by the cover-plate and regulating the air-draft, said damper-plate having its lower end, terminating short of the bottom of the box, and an oil-pipe delivering into the box at a point between the open end thereot and the 3 5 damper-plate.

2. An oil burner comprising a box-like-structure, open at the top and at one end and provided with iimovable and regulating the air draft, an oil pipe delivering into the box at a point between the oponend of the box and-said damper, and a ballie in-the bottom 01. the box between 'the point where the. oil enters the box and said damper.-

3. An oil burner comprising a hoXJlke-QtrnQture, open at the topand at one end and provided with a movable cover.-

for the open top, a damper-plate carried by the cover and regulating the air draft, an oil pipe delivering into the box at a point between the openend of the box and said damper, a bathe in the'bottom of the box between the point w-here the oil enters the box and said damper, and means independent of saldco ver for regulating the damper.

4. An oil'burner comprising a box-llke-structure, open at the topand at one end and provided with a movable cover for the open top, a damper-plate carried by the cover and I regulating the air draft, an oil pipe delivering into the box l at a point between the open-end of the box and said l damper, a bnllle in the bottom of the ho x between the point where the oil enters the box and said damper, and means including a wedge-member engageable with the damper to tilt the latter to increase or decrease the air draft opening. 5. An oil burner comprising a box having an opening 1 at one end for the admission of air and having an opening on top for the outlet of burning gases, a sliding cover for said inst-named opening, said hox closed at the rear and having an overhanging ledge proximate thereto, a dampermember crl'gi ied by said sliding Dover, an oil feed pipe, said damper cooperating with said rear end wall and said overhanging ledge whereby the current of air induced under neath said damper is deflected by said closed rear end and said overhanging ledge horizontally toward the front of CHARLES C.
